SPECIFICATION forming part of Letters Patent No. 772,137, dated October11, 1904.

Application filed. April 14, 1902. Serial No. 102,794. (ModeL) To allwhom it may concern:

Be it known that I, WVILLIAM C. DURYEA, a citizen of the United States,and a resident of Blawenburg, in the county of Somerset and State of NewJersey, have invented a new and Improved Grain-Binder, of which thefollowing is a full, clear, and exact description.

The object of this invention is to effect certain improvements in themechanism for actuating the stop and ejector arms of grainbindingapparatus.

A further object is to construct the trip devices so that they willbemore certain in operation than heretofore.

This specification is an exact description of one example of myinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a right side elevation of the apparatus. Fig. 2 is a leftside elevation thereof. Fig. 3 is a plan view of the invention. Fig. 4is a fragmentary elevation of the triparm, showing its connection withthe clutch,

said view looking from the line 4 4 of Fig.

10. Fig. 5 is a sectional view of the clutch tion of the connecting-rodbetween the drive-' shaft and the knotter-shaft. Fig. 9 is a detailsection on the line 9 9 of Fig. 2, showing the manner of mounting thesun-and-planet gearing for driving the knotter-shaft; and Fig. 10 is afragmentary plan view showing the trip-arm and its coaction with theclutch.

The rigid parts of the framing of the grainbinding'mechanism areindicated by the numeral 10 and may be of the usual or any desiredconstruction. These will not be specifically described, since they formno part of the present invention and are fully understood by personsskilled in the art.

11 indicates the drive-shaft, having cranks 12 thereon, to which thepacker-arms 14 are connected and by which they are driven in the usualmanner. 15 indicates the links connecting the packer-arms with the arms10 of the frame. 16 indicates the needle-shaft, and 17 the needle, whichis carried thereon in the usual manner. 18 indicates the knotter-shaft,19 the knotter-housing, and 20 the usual gear which drives the knotter;21, the breastplate, and the dotted line 22 indicates the deck of thebinder. All of these parts are of the usual construction and well knownin the art.

23 indicates the stop-arm, and 24 the triparm, these parts beingpositioned in the usual manner and serving the usual function, but theirconstruction and arrangement with the other elements differ according tomy invention in a manner which will now be described.

1O indicates (see Fig. 9) a boss formed on the right-hand side of thebinder-frame and disposed transversely, this boss carrying loosely theshaft 25, which forms a continuation of the drive-shaft 11 and impartsmovement to the needle and knotter shafts and their allied parts.Mounted to turn loosely around the boss 10 is a sleeve 26, and thissleeve carries an arm 27. The end of the shaft 25 projects beyond theboss 10 and carries a pinion 28, which is in mesh with a planetary gear29. This gear 29 is mounted to revolve. on the transversely-turned end30 of a rod 31, connected by a crank 32 with the needle-shaft 16. Thetransversely-turned end 30 of the rod 31 passes loosely through theplanetary gear 29 and is carried loosely in the end of the arm 27.Fastened rigidly to or formed integral with the planetary gear 29 is anarm 33, connected to the knotter-shaft through the medium of a crank 34on said shaft. The arm 33 has at opposite edges hooks 35, which areplaced out of transverse alinement with each other and are adaptedrespectively to engage with studs 36 on the binder-frame, thisengagement being alternatethat is to say, one hook engaging itscorresponding stud and then disengaging it, while the other hook beginsits engagement with the corresponding stud. These hooks and studs formtemporary fulcra for the rod 33, which during these periods istransformed into a lever. Fig. Sillustrates diagrammatically the rollingaction of the arm and the R0- v contrary to the action of the spring 41.

man numerals I II III on this view show the successive positions taken,from which it will be seen that the rocking movement begins with thehook fully engaged with the stud and during the rocking movement thehook is gradually disengaging the stud. Now as the shaft turns anddrives the gear 28, ow ing to the arrangement of the parts 26, 27, 29,and 33, the arm 27 and gear 29 are caused to sweep around the gear 28.This imparts a rotary motion to the knotter-shaft and a rocking motionto the needle-shaft. It will be observed that the rod 31 serves not onlyto drive the needle-shaft, but as a center for the planetary gear 29. Asthe arm 33 moves upward it engages the lower hook with the correspondingstud 36, and the arm then rocks around this stud as a lever. As the armmoves down the upper hook 35 engages the corresponding stud and the armagain rocks as a lever.- By this means I am enabled to get the necessaryforce for driving the knotter-shaft and to turn the crank 34 past thetwo deadcenters, which it necessarilytakes with respect to theknotter-shaft and the driving force. It of course will be understoodthat the parts 35 and 36 must be carefully positioned relatively to eachother, so that engagement at the proper time will take place. Thismechanism provides a direct and powerful means for driving theknotter-shaft and dispenses with the long train of gears andcomplicatedclutch common to this part of binders as usually constructed.

As shown best in Figs. 3, 5, and 10, the

adjacent ends of the shafts 11 and 25 closely approach and are adaptedto be connected by a modification of the Appleby clutch, which comprisesa sleeve 37, keyed to the shaft 25 and having a radially-projected stud38, carrying a dog 39, which coacts with the disk member 40, keyed onthe drive-shaft 11. The dog 39 projects outward beyond the clutch-disk40 and is thrown into active position by means of a spring 41. (See Fig.6.) 42 indicates a stop-arm which is adapted normally to engage the dog39 and hold it inactive The engagement of the parts 39 and 42 is bestshown in Fig. 4. WVhen these parts are disengaged, the spring 41 throwsthe dog 39 into engagement with the disk 40, and the shafts 11 and areconnected. The stop-arm 42 is mounted on a short transverse shaft 43,which itself is carried in a part of the frame 10 and in a bracketlO,fastened to said frame part. 44 indicates a spring bearing between thisbracket 10 and stop-arm 42 through the medium of a rod 45, to which thespring and stop-arm are connected, and this spring 44 tends normally tohold the arm 42 in active position c'. (3., engagement with the dog. Tothe outer end of the shaft 43 the trip-arm 24, before mentioned, isfastened, andat this point on the rod 43 is also fastened a short arm46,

i of the arm 46.

which projects under the needle and carries a roller 47, adapted toengage with a tail-cam 48 on the butt of the needle. Now when thepressure of the gavel on the trip-arm becomes sufficiently great it willthrow the trip-arm down, and it will also raise the arm 42, thuspermitting the spring 41 to engage together the members of the clutch.The shaft 11 turns continuously, working the packer-arms in the usualmanner, and when the members of the clutch are engaged the shaft 25turns. This shaft by means of the gearing before described immediatelystarts the action of the needle and the knotter shafts, and the instantthat the needle begins to move it rides the tailcam 48 under the roller47, and thus it holds the arm 42 raised through the medium The needlemoves up around the gavel during this period and returns, the arm 42being held inactive until the needle comes to rest at the end of themovement, whereupon the cam 48 runs off of the roller 47, and the spring48 immediately throws down the arm 42, thus breaking the connection ofthe clutch-members and stopping the movement of the needle and knottershafts.

The stop-arm 23 is pivotally mounted at the point 49 on an elbow-lever50, and a stout spring connection is effected between these parts 23 and50 by means of a spring 51 and rod 52. This allows the stop-arm 23 toyield slightly with respect to the elbow-lever 50. The elbow-lever 50 ismounted to turn around the center 53, and its other arm carries a roller54, which engages a cam 55 on the knottershaft. This cam, as best shownin Fig. 1, is approximately half-circular, and it gradually increases inradius from the end 55 to the end 55. Assuming the parts to be in theposition shown in Fig. 1, as the knotter-shaft 18 turns it drives thecam 55, and the increase of radius of this cam slightly presses down theelbow-lever 50, and consequently the stoparm. This causes the stop-armto assist in pressing the gavel, said arm moving contrary to theadvancing needle, and thus the parts hold the gavel snug during theknotting operation. Finally, when the cam 55 runs off of the roller 54the stop-arm is released and is allowed to swing, with the elbow-lever,upward, so as to permit the bundle to be ejected.

56 indicates a coil or other spring which is connected to the lever 50and tends to throw the same upward, (see Fig. 7,) so that the instantthe cam 55 releases the elbow-lever it will move with the stop-arm intoinactive position.

57 indicates the two ejector-arms. These arms are carried,respectively,.on the knottergear 20 and the cam 55 and are in transversealinement, as the drawings indicate. They are so positioned thatimmediately after the release of the stop-arm the ejector-arms willsweep downward, engaging the bundle and throwing it from the machine.

The general operation of the apparatus may be traced as follows: Thedrive-shaft 11 turns continuously, and the packer-arms are workingsteadily to force the grain. VVhen the pressure on the trip-arm 24becomes sufficient, the trip-arm is depressed and the clutch members areallowed to become active, whereupon the shaft 25 turns. This movement ofthe shaft causes the planetary gear 29 to be swept around the gear 28and the proper movements are thereby imparted to the needle and knottershafts. The needle moves up, and then the cam 48 holds the arm 42inactive. As the needle moves up the cam 55 causes the stoparm 23 tomove slightlytoward the needle. During this period the knotter mechanismis active and the knot is tied. Then the cam 55 runs off of the roller54, and the stop-arm moves upward under the action of the spring 56,whereupon the ejector arms 57 move against the bundle and sweep it fromthe machine. Meanwhile the needle is falling back to its inactiveposition, and immediately upon the assumption of this position the arm42 descends and throws back the dog 39, thus stopping the movement ofthe shaft 25.

The knotter and its operative gear may be of any desired constructionand forms no part of the present invention, for which reason I have nothere illustrated it. The same is true of the various frame parts and theother adjacent parts of the binder mechanism, including the deck, thebreastplate, and such parts, all of which are preferably the same asthose usually employed.

Various changes in the form and details of my invention may be resortedto at will without departing from the spirit of my invention. Hence Iconsider myself entitled to all forms of the invention as may lie withinthe intent of my claims.
